. DOUGH-KAISER.

Patented Nov. 26, 1912.

Application filed November 22, 1911. Serial No. 661,739.

To all whom it may concern:

Be it known that I, MAUD M; BILLINGS- LEY, a citizen of the UnitedStates, residing at Beaver Falls, in the county of Beaver and State ofPennsylvania, have invented a new and useful Dough-Raiser, of whichthefollowing is a specification.

This invention relates to dough raisers, and has for its object theprovision of a device, which is adapted to maintain dough in preparatorystages of bread and cake making at an equable temperature, and one calculated to facilitate the fermentation process and the resultantexpansion or rising-of the same.

such manner as to preclude the exposure of the dough to dust laden airand contamination from other causes.

. Having these objects in View, the invention resides in the particulararrangement and construction and combination of parts hereinafterparticularly claimed and which will now be described in detail inconnection with the accompanying drawing, wherein is shown a preferredembodiment of the invention.

In the drawing :Figure 1 illustrates the device in perspective with aportion of the cover broken away. Fig. '2 is a horizontal section on theline 2-2 of Fig. 3. Fig. 3 is a vertical longitudinal section. Fig. 4 isa detail perspective of one of the spacing bridges.

The device as illustrated consists essentially of an outer vessel 1,provided in its lower portion with a spigot 2. Within this outer vesseltransversely arranged spacing bridges 3 are disposed, each consisting ofa bar having a length substantially equal to the inner width of thevessel 1 and upturned at the ends to form studs 4. WVithin the outervessel an inner vessel 5 is arranged resting upon the spacing bridges 3and confined laterally between the studs 4. This inner vessel is ofsubstantially the same shape as the outer vessel, but is of less depthand also of less width and length so that when disposed within the outervessel upon the bridges 3, the upper edges of the two vessels will be insubstantially the same horizontal plane and the side and end walls willbe spaced apart a distance corresponding approximately to the spacebetween the bottom walls due to the interposed spacing bridges. Theinner vessel is provided preferably with A further object is to effectthis result in" a marginal outwardly extending flange 6, which bridgesthe interspace between the slde and end walls, and is downwardly flangedat? to embrace said walls on the exterior. This flange is provided witha fillmg opening 8 for the interspace, said opening being normallyclosed by a pivotally mounted cap 9. Upon the bottom of the inhervessel'is disposed a wire mat 10, formed of coarsely woven wire andsuspended with in the upper portion of the inner vessel by the hooks 11is a tray 12 of wire. A cover 13 having an upwardly tapering centralportion is provided with vents 14L and is of a size to extend to theouter edge of the flange 6 in embracing relation to the flange 7 so asto wholly cover both vessels and the hooks 11.

The device is advantageously used as follows: The flour is first placedwithin the inner vessel and the interspace between the walls filled witha heating fluid, such as hot water, the cover being placed in position,when the chill is taken off the flour and it is brought into a favorablecondition to receive the leavening material. After the sponge is made upit is placed in a suitable pan within the inner receptacle and the coverbeing replaced allowed to stand and rise. When the proper stage has beenreached, it is again removed and kneaded into loaves and having beenplaced in the bake pans is again placed in the inner receptacle upon themat, which serves to space the pans from the heated bottom and permit acirculation 'of air beneath the same. When ready for baking, the loavesare removed and transferred to the oven. During the several steps of theprocess, it will be observed that the dough is entirely inclosed andshielded from dust and from cold drafts of air, while the body of hotwater surrounding the inner vessel maintains the same at an equabletemperature. The provision of the draw-off spigot 2 and the fillingopening 8 enables the water to be drawn oft and replaced in whole or inpart at any time without disturbin the inner vessel or its contents, sothat curing a long period of time the water may be changed to maintain aproper temperature. The tray arranged in the upper part of the vesselenables the inner vessel to be employed at the same time for the raisingof the doughin itslower portion and for the raising of additionalquantities of the same or a different kind of dough in the upper portionof the vessel. When not in use the two vessels are easily separatedpermitting their drying and cleaning, and the wire mat and tray arereadily removed from the inner vessel for cleansing purposes. Thecomponent parts are of simple construction andthe device as a whole isexceedingly eflicient for the purposes intended, it being also adaptedfor use as a receptacle for the newly baked bread to maintain the sameor other cookery products in a warm condition.

What is claimed is In a dough raiser, an outer vessel, an inner vesselof smaller dimensions in readily separable relation to the outer vesseland having an upper marginal outturned flange terminating in a dependingflange adapted to surround the upper marginal portions of the walls ofthe'outer vessel with the outstanding flange'resting on the upper edgesand rising therefrom toward the center'of 4 the cover in spaced relationto the outstanding flange of the inner, vessel, the dough raiser beingalso provided with a wire tray provided with suspension hooks adapted toengage over the outstanding flange of the inner vessel between the sameand the corresponding portion of the cover.

In testimony, that I claimthe fore-going as my own, I have heretoaflixedniy signaturein the presence of, two witnesses.
